Geothermal

The U.S. Environmental Protection Agency has identified geothermal heat pump systems, also known as “geo exchange” as the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available.*

A Geothermal Heat Exchange system for heating and cooling uses the earth for energy storage and extraction. It is not only a sustainable technology, but one that offers significant energy and cost savings.

How does it work? Basically, an electric heat pump circulates an environmentally friendly anti-freeze solution through a heat exchanger which is series of polyethylene pipes buried in the ground. The system utilizes the earth’s average ground temperature of 50-55 ° F to cool the fluid in the summer and warm it in the winter.

The transfer of energy from the building through the earth and back the building is one of the most efficient means of heating and cooling.

The thermal transfer takes place through polyethylene pipe, the artery for the system. Outstanding integrity and performance are integral to the system.

Types of Configurations

There are four common types of geothermal heat exchange configurations.


Vertical Well Systems


Pond Loops


Horizontal Straight Loop


Slinkys

A Leader in Geothermal

Charter Plastics is recognized as an industry leader, having produced premium quality geothermal pipe for over 20 years.

Charter’s geothermal pipe has been used extensively in residential installations, commercial buildings, schools, universities and federal facilities.

Charter uses High Density Polyethylene Pipe (HDPE), which is a smart environmental choice. Polyethylene pipe takes less energy to produce than equivalent metal piping products. The pipe is relatively light-weight, and requires less energy to transport.

It is flexible and can be joined with heat fusion requiring fewer fittings and providing permanent leak-free systems. At end of life, polyethylene pipe can be recycled and put back into non pressure piping applications.
